title: "Temporary prosthesis" of the fibrotic ring for relative insufficiency of the tricuspid valve.
abstract: BACKGROUND
  De Vega type suturing dosage plasty is the intervention most widely used for relative insufficiency of the tricuspid valve (TV). In fact, this operation may be considered as an equivalent of prosthetic reconstruction of the fibrotic ring, shaping a fixed orifice for passage. Intrapulmonary pressure normalized as early as during the first months after surgery in patients with the mitral-tricuspid cardiac valvular disease. Under such conditions a rigid suture (prosthesis of the anulus) at the interface of the right atrium and ventricle is not physiological.
  
  
  METHODS
  We used Maxon CV 2-0 (D+G) suture absorbable for 6 months. Xenopericardial pads were fixed at the edge of the suture. The pads were prepared by enzymatic and chemical processing.
  
  
  RESULTS
  Operations were performed in 7 patients, the results were followed for up to 28 months. The size of the TV fibrotic ring was measured by transesophageal ultrasonography (Hewlett-Packard SONOS 1500; OMNIPLANE) on the operating table and for 2 years postoperation. No signs af tricuspid insufficiency were detected.
